Water Treatment
We treat Lake Michigan water at two plants, passing the water through multiple treatment process barriers that keep illness-causing microorganisms from our drinking water.

The primary form of disinfection is ozonation, in which ozone gas is bubbled through the water. The highly reactive gas destroys illness-causing microorganisms, controls taste and odor, and reduces chlorinated disinfection byproducts. Following inactivation of microorganisms, the processes of coagulation, settling, and filtration remove additional particles.
